1. Real-time DDoS Attack Monitoring for Predictive Analytics Models


    Real-time DDoS (Distributed Denial of Service) attack monitoring is vital for protecting your cloud resources from malicious attacks that can disrupt your services. To set up DDoS attack monitoring with Pulumi, we can deploy resources that provide insights into your network traffic and include protection plans to mitigate these kinds of attacks.

    In this program, we will use Azure as our cloud provider and set up a DDoS Protection Plan to protect our Azure virtual network. Azure DDoS Protection, combined with application design best practices, provides defense against DDoS attacks. The DDoS Protection Plan is a feature that provides enhanced DDoS mitigation capabilities for your application and resources to your virtual network.

    Here's how we will proceed:

    1. Create a Resource Group: Azure resources need to be grouped together in a resource group.
    2. Set up a Virtual Network (VNet): This is the network where your cloud resources will reside, and what we'll be protecting with the DDoS Plan.
    3. Set up a DDoS Protection Plan: This will provide DDoS protection to the resources associated with the virtual network.

    Below is a Pulumi program in Python that accomplishes the setup:

    import pulumi import pulumi_azure_native as azure_native # Create a resource group for our resources. # This groups our resources together and allows us to manage the lifecycle of all the resources together. resource_group = azure_native.resources.ResourceGroup('resource-group') # Create a virtual network. # This is the network that our resources will be connected to. # Replace the `address_space` with the one that suits your architecture. vnet = azure_native.network.VirtualNetwork( 'vnet', address_space=azure_native.network.AddressSpaceArgs( address_prefixes=[''], ), resource_group_name=resource_group.name, ) # Create the DDoS Protection Plan. # This plan will be associated with the virtual network to provide DDoS protections for the resources in the vnet. ddos_protection_plan = azure_native.network.DdosProtectionPlan( 'ddos-protection-plan', location=resource_group.location, resource_group_name=resource_group.name, ) # Associate the DDoS Protection Plan with the Virtual Network. # This tells Azure to protect this particular vnet with the specified DDoS Protection Plan. vnet_with_ddos_protection = azure_native.network.VirtualNetwork( 'vnet-with-ddos-protection', virtual_network_name=vnet.name, ddos_protection_plan=azure_native.network.SubResourceArgs( id=ddos_protection_plan.id, ), enable_ddos_protection=True, # This flag enables the actual protection. resource_group_name=resource_group.name, location=resource_group.location, address_space=vnet.address_space, depends_on=[ddos_protection_plan], # Ensure the DDoS Protection Plan is created before associating. ) # Export the IDs of the resources. # These can be used to reference the resources or connect other services to them. pulumi.export('resource_group_id', resource_group.id) pulumi.export('vnet_id', vnet.id) pulumi.export('ddos_protection_plan_id', ddos_protection_plan.id)

    This Pulumi program creates a DDoS Protection Plan and associates it with a Virtual Network in Azure using the azure_native module. Be sure to replace the address prefixes and any other configuration details with values that match your specific requirements.

    • The ResourceGroup is the container that holds related resources for an Azure solution.
    • The VirtualNetwork defines the network space for Azure cloud resources, in which your cloud workloads will run.
    • The DdosProtectionPlan is the service for DDoS protection that is associated with our virtual network to protect it from DDoS attacks.

    Each resource is represented by a class that accepts arguments specifying the configuration details of that resource. Once the program is executed with the Pulumi CLI, the defined resources will be provisioned in Azure.

    To try this out, make sure you have Pulumi and the Azure CLI configured with appropriate access to your Azure account. Save the above code in a Python file (for example, ddos_monitoring.py), and run it using the Pulumi CLI commands pulumi up. This will show you a preview of the resources that will be created, at which point you can choose to proceed to deploy the resources.
